2.3. Description of the unit

This section describes the physical look of the PLEXTALK and the layout of the keys and

other controls to enable you to locate them when referred to in later chapters. The names

and main purposes are also detailed here.

While carefully holding the unit, take a few moments to locate the front of the unit. The

front has the microphone and speaker grill at one end and 23 keys arranged across the

rest of the surface. Turn the unit so that you are holding it with the keys uppermost and

with the grill away from you. The PLEXTALK should now be set up in its normal operating

position. Keep the unit in this position as the physical layout is described.

2.3.1. Front face

The grill that you used to orientate the unit is where the internal speaker and the built in

microphone are located. The speaker is on the right and the microphone is in the center.

Just below the grill, in the center, there are 2 LEDs. The one on the left is the Power LED.

It should be off when the unit is turned off. It becomes orange while booting up. It shows

green when the unit is on. The one on the right is the Battery LED and indicates the

charging status. It is off when the PLEXTALK is operating on battery power. During

charging Phase 1, it will show a red light. During charging Phase 2, it will alternate

between red and green, and when the battery is fully charged, it turns solid green.

Below the grill, to the left and right of the LEDs, there are two oval buttons. The key on the

left is colored red and is the Record key, used for DAISY recording, Voice memo

recording and for recording Voice Bookmarks. The key on the right is colored green and is

the Power key, used for power on/off and for setting the sleep timer. In the center of this

key there are two prominent tactile dots.

Below the Record key and the Power key, there are 4 function keys: 2 on the left and 2 on

the right of the unit. The upper left key is the GoTo key, used for page and heading

navigation. The lower left key is the Bookmark key, used for bookmark navigation,

insertion and deletion. The upper right key is the Menu key, used to access the main

menu. Press and hold this key to turn on or off the Key Describer mode. The lower right

key is the Title key, used for changing the title or media.

In between the 4 function keys, at the center of the unit, is the circular Play/Stop key

surrounded by four arrow keys: Up, Down, Left and Right. The Play/Stop key is slightly

indented and is colored blue. It is used to start/stop playback and acts as the Enter key for

some operations. The Up key is used for moving up in the list of navigation options. It is
